Abstract (en)
[origin: WO0222300A1] The present invention pertains to low temperature pressure consolidation methods which provide for bonding of target material (10) to the backing plate material (15) capable of withstanding the stresses imposed by high sputtering rates. The sputter target assemblies in accordance with the present invention are preferably comprised of target materials and backing plate materials having dissimilar thermal expansion coefficients and incorporate internal cooling channels (20). In the preferred embodiment, the resulting bond (35) and the formation of the cooling channels (20) are cooperative.
